This one is a real puzzle - what station is this? There is a C-QUAM (AM stereo) Dutch station on this frequency called "Dreamtime AM" but it's a low power station and this one is booming into the Grimsby UK SDR around 200 miles away. The sound of the audio sound like other C-QUAM stations I've heard on a normal AM radio. Any answers are a help.
